Given the limited amount of information posted here (no version, platform, other details), its a real challenge (but fortunately I like a challenge...)!
If I've calculated correctly, that probe comes out when a windows queue manager tries to create a named pipe and it fails (Probe 40 from zcsPipeCreate). It is quite rare of that call to fail, and not many causes - the only times it has been seen all turned out to be caused by external influences. A number of times stopping something called SWIFT application services avoided the problem (apparently there's a SWIFT update to it to fix this), although I have no idea what SWIFT Application Services are... If you are not running SWIFT, then you will need to open a PMR with IBM to debug further, although I would recommend updating this question with your full FDC header just in case anything else stands out.
The test program referred to in the link #JoshMc gave is as follows - perhaps try this?
#include <windows.h>
main()
{
HANDLE hnp;
int rc=0;
hnp = CreateNamedPipe("\\\\.\\pipe\\1\\TESTQMGR\\zsocketEC\\Zagent",
PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE|PIPE_WAIT, 1, 1024,1024,
NMPWAIT_USE_DEFAULT_WAIT, NULL);
rc=GetLastError();
if( hnp == INVALID_HANDLE_VALUE )
printf("CreateNamedPipe failed with %d ",rc );
else
printf("NamedPipe created successfully");
}
